ABSTRACT


We present a multi beam gamma ray computed tomography (CT) scanner design for multi-phase flow investigations in industrial apparatuses. It mainly comprises a collimated 137Cs isotopic source and an in-house developed detector arc with overall 16 scintillation detectors offering a quantum efficiency of approximately 75% and an active area of 10×10 mm2 each. The detectors are operated in pulse counting mode to enable gamma photon energy discrimination. A key element for highest flexible application of the proposed CT scanner is the elaborated detector design that is concerted with a sophisticated scanning procedure that allows for multi beam projection acquisition. Thus, scanning times can be adopted to various object sizes to save measuring times while the arrangement of source and detector arc remains identical.
